Book publisher Hachette is no longer in a blood feud with Amazon, but it's already experimenting with new, Bezos-free online selling options, just in case. The latest: An experiment where best-selling Hachette authors will be able to sell their books directly to fans on Twitter.

Hachette is partnering with Gumroad, a company that helps people sell stuff on Twitter. The first patch of authors includes crowdfunding enthusiast Amanda Palmer, gentle Canadian astronaut Chris Hadfield, and The Onion. There will be a "buy" button so people won't have to leave their feed to spend money on books.
